FUEL SYSTEM
Visual inspection of fuel system components
reduces the
possibility of undetected fuel system
leaks. Inspect fuel system components regularly.
~ WARNING ~
Failure to check for fuel leakage could
allow a leak to go undetected, resulting in
fire or explosion.
Fuel Filter
Johnson outboards are equipped with a service-
able fuel filter element. Clean or replace the ele-
ment as needed. Refer to FUEL PUMP on p. 149.

Air Silencer
The air silencer on Johnson outboards minimizes
audible noise related to air flow into the engine.
Additionally, it collects any fluid residue that
migrates from the
leaf plate or the throttle body
area.
Periodically clean the air silencer to remove
any
accumulations.
